“…Also release of products at elevated pressures mitigates the parasitic losses associated with the compression of the H 2 or syngas products. Furthermore, the typical high H 2 to CO ratio of the SWCG process can further contribute to the economic viability of the process (Gutiérrez Ortiz et al, 2013;Pinkard et al, 2018). Nonetheless, despite the aforementioned potential benefits, several operability challenges remain to be addressed to achieve economic viability at commercial scales, including char formation, inorganic salt deposition, and material compatibility requirements for high-pressure and high-temperature operation (Ciuffi et al, 2020;Gutiérrez Ortiz, 2022).…”

“…Recently, glycerol steam reforming has been researched under supercritical water conditions with or without the presence of a catalyst [59][60][61][62][63][64][65]. Markoḉiḉ et al [63], in their review article, explained that supercritical water condition means the operating pressure and the temperature exceeds the water critical point, i.e.…”

The catalytic steam reforming of oxygenated hydrocarbons has been holding an interest in scientific societies for the past two decades. The hydrogen production from steam reforming of glycerol, ethanol and other oxygenates such as ethylene glycol and propylene glycol are more suitable choice not just because it can be produced from renewable sources, but it also helps to decrease the transportation fuel price and making it more competitive. In addition, hydrogen itself is a green fuel for the transportation sector. The studies on the production of hydrogen from various reforming technologies revealed a remarkable impact on the environmental and socio-economic issues. Researchers became more focused on glycerol steam reforming (GSR), ethanol steam reforming (ESR) and other oxygenates to investigate the catalyst suitability, their kinetics and challenges for the sustainability of the oil and gas production. In the present work, the authors critically addressed the challenges and strategies for hydrogen production via GSR, ESR and other oxygenates reforming process. This review covers extensively thermodynamic parametric analysis, catalysts developments, kinetics and advancement in the operational process for glycerol, ethanol and few other oxygenates. This detailed investigation only highlights the steam reforming process (SRP) of these oxygenates at the laboratory experimental stage. It was found that from this review, there are many technical issues, which lead to economic challenges. The issues are yet to be addressed and thus, these particular applications require faster accelerations at the pilot scale, taking into the consideration of the current pandemic and economic issues, for a safer and greener environment.

“…In case of the hybrid systems, for both compressor and turbine, an isentropic model is used. Isentropic, mechanical and generator efficiencies of η isen = 72%, η mech = 100% and η gen = 98% were assumed, respectively , . For both hybrid systems (pressurized and atmospheric), the pressure ratio defined with

Modeling of a Novel Atmospheric SOFC/GT Hybrid Process and Comparison with State‐of‐the‐Art SOFC System Concepts

et al. 2020

A novel concept for an atmospheric solid oxide fuel cell (SOFC) hybrid system applying a sub-atmospheric gas turbine is proposed. Based on a developed process model suitable operating conditions are studied. The resulting performance is compared to different state-of-the-art SOFC system concepts. The comparison shows that pressurized SOFC/GT systems offer the highest electric efficiency. The novel concept as well as a two-stage SOFC system offer lower efficiencies, but still well above 60%. However, avoiding the complex system requirements of pressurized SOFC/GT systems, these concepts are promising for highly efficient electricity generation.
